   Network Virtualization Overlay (NVO) networks using EVPN as control
   plane may use Ingress Replication (IR) or PIM (Protocol Independent
   Multicast) based trees to convey the overlay BUM traffic. PIM
   provides an efficient solution to avoid sending multiple copies of
   the same packet over the same physical link, however it may not
   always be deployed in the NVO core network. IR avoids the dependency
   on PIM in the NVO network core. While IR provides a simple multicast
   transport, some NVO networks with demanding multicast applications
   require a more efficient solution without PIM in the core. This
   document describes a solution to optimize the efficiency of IR in NVO
